Cisco 850 config question

I have configured a new Cisco 850 router for use with my network. Everything seems fine except for one lingering issue: I can't get to certain web sites.

- I am using NAT for resolving ip addresses to my web server and email server and that works fine.
- I have firewall settings set to 'high' and everything seems normal.

I can get to almost every web site I try with a few exceptions:
- I can't get to anything on Yahoo.com
- I can't log in to this web site experts-exchange.com (I am using a different location to write this).
- I can't get to Kodak's Easy Sharre web site
- plus a few others

I don't really care about the web sites themselves, but I think there is an underlying issue with the router that is causing the problem. Could someone please take a look at the config file and let me know if there are any obvious problems.

Thanks.

Are you sure you don't have any other software on your computer that could limit your access to those websites ?
 Maybe there is a policy not to allow users on those websites set up on the server or on each machine individually.
 Any AV, firewalls ... installed ?

I thought about stuff like that and I don't believe there is anything locally that would stop it. Before I implemented the Cisco router, I was using a Linksys and this problem didn't exist. If I switch back to the linksys router, I can access these sites.

The worksations are  using windows 2000, no firewall, I removed the AV and the problem still exists. I ran Ad-aware and cleaned up the pc's and the problem still exists. It is the same for all of the workstations so I really don't think it is a local problem. All of the ps'c go through the router and they all have the same issue accessing certain websites.

I also think it has something to do with permissions or scripting or something. Because I can get to eveything on the Experts Exchange website as a guest but when I try to log in, I don't get any errors, it just keeps brining me back to the login page.

For instance, at the Kodak web site, I can see the preview, but when I try to log in to see the slideshow, I get an error saying the page timed out. It will never let me log in.

I don't know what the heck is going on with Yahoo. I can't get to a single page that ends in yahoo.com.

There are handful of other sites that I have problems with but about 99% of the web pages I go too are fine. I can log into other sites just not EE (and apparently Kodak).

I'm not familiar enough with Cisco configs to start experimenting and poking around so I was hoping someone could look at the config and say 'you need to remove this line' or 'change this setting because that will cause your problem.'

if you remove the policy what happens ? is it ok ?
 Router(config)# no appfw policy-name SDM_HIGH
I'll check and let you know.

Thanks.
neos2k1,

Thanks for the suggestion, but that did not change anything.

Hello section25, could you please post the commands that you used in your Cisco to solve the problem? I'm gettiing the same issues in my Cisco851, but I cannot find the commands to be set on it.

Thanks
